Homozygous plants have two identical copies of a single gene. Heterozygous plants have two copies of a single gene, but those copies are alleles, or different versions of that gene. Example of alleles controlling a trait for susceptibility to a lesion-causing disease.
Best Answer: Miley's dad is Billy Ray Cyrus. He is a country singer who also plays the guitar.

Before Billy Ray Cyrus became a household name in 1992 with the release of the #1 single Achy Breaky Heart (and later as dad to Miley, which by the way, was one of the fastest rising names of 2007), the most famous American Cyrus was President Jimmy Carter's Secretary of State Cyrus Vance.
